使用 virtualenv 恢复 `--no-site-packages` 选项 [英] Revert the `--no-site-packages` option with virtualenv

问题描述

我使用 --no-site-packages 选项创建了一个 virtualenv 并安装了许多库.现在我想恢复 --no-site-packages 选项并使用全局包.

I have created a virtualenv using the --no-site-packages option and installed lots of libraries. Now I would like to revert the --no-site-packages option and use also the global packages.

我可以在不重新创建 virtualenv 的情况下做到这一点吗?

Can I do that without recreating the virtualenv?

更准确地说:

我想知道使用 --no-site-packages 选项而不是不使用该选项创建 virtualenv 时究竟会发生什么.

I wonder what exactly happens when creating a virtualenv using the --no-site-packages option as opposed to not using that option.

如果我知道会发生什么，那么我就能弄清楚如何撤消它.

If I know what happens then I can figure out how to undo it.

推荐答案

尝试删除(或重命名)您的 Lib 中的文件 no-global-site-packages.txt> 虚拟环境下的文件夹.

Try removing (or renaming) the file no-global-site-packages.txt in your Lib folder under your virtual environment.

其中venv是你的虚拟环境的名字，python3.4对应的是python的哪个版本，例如:

Where venv is the name of your virtual environment, and python3.4 corresponds to whichever version of python involved, for example:

$ rm venv/lib/python3.4/no-global-site-packages.txt

如果你改变主意并想把它放回去:

And if you change your mind and want to put it back:

$ touch venv/lib/python3.4/no-global-site-packages.txt

注意:如果您没有看到上述文件，那么您有一个较新版本的 virtualenv.你会想要关注这个答案

Note: If you don't see the above file, then you have a newer version of virtualenv. You'll want to follow this answer instead
